swag v2 support generate openapi v3.1 docs, but gin-swagger not support.

I referred to the design of gin-swagger and simplified the use of gin-swagger.

Now just copy the following two files to your project:

openapi/register.go
openapi/swagger-initializer.js

In this way you can make some custom modifications according to the needs of the project.

1. install swag v2

   go install github.com/swaggo/swag/v2/cmd/swag@latest
   

2. generate openapi v3.1 docs

   swag init --v3.1 --output ./openapi --outputTypes json
   

   generated openapi/swagger.json file, and ignored by .gitignore not push to git repo.

3. run app

   go run main.go
   

4. view docs open http://localhost:8080/openapi in browser.

Enjoy!
